Equation that includes only the compoments directly involved in the reation.

Question 22

synthesis

Answer 22

A + X = AX

Two or more substances combine to form a new compound.

Question 23

decomposition

Answer 23

AX = A + X

A more complex compound reacts to form two or more simple compounds.

Question 24

single displacement

Answer 24

A + BX = B + AX

Y + BX = X + BY

One element replaces a similar element in a compound.

Question 25

double displacement

Answer 25

AX + BY = AY + BX

The ions of two compounds trade places in an aqueous solution to form two new compounds, one of which is usually a solic, liquid, or gas.
